PRO: The PStart key (new) works. IF i set 1, then it does PSate1(9*) ...PSate3(6*)

PROBLEMS:

1. Even if i set butratio=9 (my BIOS setting, FSB is detected right as 333 MHz) the System (all MHZ Tools) showing 3333 MHZ as if busratio would be 10*, should be 3000 Mhz (9*333)

CPU: Multipliers x10: max=100, min=60

CPU: MaxDiv/CurrDiv: 0x0/0x0

CPU: TSCFreq: 3330MHz // wrong, busratio set to 9

CPU: CPUFreq: 3330MHz

CPU: FSBFreq: 333MHz // OK

Pstates generated in this case as 3000 MHz (9*) down to 1999 MHZ(6*) = OK! PStart=1 was computed OK, which (avoids 10*)

P-State: Added [Frequency 1998 MHz, FID 0x6, VID 0xe5]

2. The moreVolt key, i set to 40 (40mV more each Pstate) seems to produce unusable values (since it was implemented)

Normaly they were 1x...2x (hex), i get E5 to EA (sure not OK!)

3. maxVolt key seems have no effect ?

Voltage: min= 1037mV, max= 1112mV / i set it to 1248mV

4. What does this mean ?

Found ACPI CPU: CPU0

Found ACPI CPU: CPU1

Found ACPI CPU: CPU2

Found ACPI CPU: CPU3

I only have C2D , no Quad CPU ?! Also the OS X boottext shows only 2 CPUs enabled.

PICS:

1. PSate=1, maxVolt=40, busratio=9 (VIDs bad), PStart worked)

2. busratio=9 (VIDs bad)

3. normal RC5 autogen (VIDs OK)

4. my .plist

mitch_de · November 20, 2010

Even if i disabled PStates gen in 5.0.5 + using handmade dsdt, the CPU freq stays wrong (FSB OK detected, busratio=9)

back to RC5 boot, Pstate gen OFF, handmade dsdt Pstates, leaved all other (for RC5 unknown new keys unchanged)

Now CPU freq is OK - no changes in the settings!!!!

That CPU freq problem must be new, i remember that wasnt using 5.0.1 or 5.0.2 (using also busratio=9).

Q: Is the value of CPUFreq that value which changes by Pstate working ?

I ask because if yes, we can use sysctl hw.cpufrequency to show that without need other tools (MSR didnt work for me, Systemprofiler shows always the other Cpu max.Freq (fixed max)).

With the latest nightly of Chameleon I get a score of 8400 in geekbench, and with the latest version of your bootloader I get a score of 8000..

With the system in my sig.

EDIT: And with P-States generation enabled I only get a score of 4000 in geekbench

Carstiman · November 20, 2010

"i OC to 3840 Mhz only with FSB 333 and vcore to 1296 mV
is there a easy way for me to get the pstate steps working in OC mode ?"

Yep, valv does some major steps for the OC+ autogen Pstate customers!

For my knowledge wie must use an combination of maxVolt= , to make higher CPU Volt possible and moreVolt= which does add some mVolts to each Pstate (to reach same mVolt you had before with handmade DSDT Pstates).

valv also added some usage examples to each key - much thanks!

Other people, which do also OC but also change busratio beside FSB may also need to use busratio= and PStart= (NEW in 5.0.4+) to avoid using the non available Pstate0, if busratio was set one step down (10>9) . I use OC : 9*333 (normal 10*266) so i had to use also PStart=1 to avoid PState0=10* autogeneration (if not KP because 3333 Mhz - to much for my 2666 MHz C2D).

I will try that now with the 5.0.5 Version / Gigabyte EP35-DS3 / C2D E7500OC and report!

UNCLEAR: I read in some other postings that the VID Problem also depends from the BIOS/Mainboard vendor and handling of CPU Volts settting (auto/normal vs. more Volts in BIOS). Most OCer will have set higher VID in the BIOS for OC.

It can be, that at least at boottime (before bootloader+OS X sets up OCed VIDs) its needed to overVID in BIOS. Also it can be that the BIOS overVID does block / disallow any VID changes by the Pstates VID changes later.

Would be nice if some coder here can tell something about that

To all i cut out the OC related keys from the new helpfile.txt (within the .zip)

GeneratePStates=Yes Automatically generate supported CPU P-States (default: disabled).

Overclocking Options: (To use with CAUTION!)

--------------------------------------------

PStates=<value> Maximum number of P-States to generate (default: all);

e.g.: 8 to generate the 8 highest Frequency states only.

PStart=<value> The highest Frequency state to start from (default: 0);

e.g.: 1 to start from P1.

busratio=<value> Alter bus ratio - e.g.: 8.5 (default: auto).

minVolt=<value> Under-volt the processor to the specified value (mVolt);

e.g.: 1100 for 1.1 V

maxVolt=<value> Over-volt the processor to the specified value (mVolt);

e.g.: 750 for 0.75 V

moreVolt=<value> how much mVolts to add to each step;

e.g.: 20 for getting additional 0.02 V for each CPU state

lessVolt=<value> how much mVolts to take-out from each step;

e.g.: 10 to substract 0.0.1 V from each CPU state

tried your settings and played around with it.

i lost one P-State:

Same here. Also with OS X 10.6.5 I presume?

edgar87 · November 20, 2010

OS X 10.6.5 I presume?

Yep, 10.6.5, why?

This is my boot.plist:

com.apple.boot.plist.zip

Time2Retire · November 20, 2010

Yep, 10.6.5, why?

This is my boot.plist:

Apple may have changed their OSPM code for (certain) Intel Core iN CPU's. Went back to OS X 10.6.4 to check (with the same booter and P_States) and everything is fine again.

Too bad that MSR Tools only shows two cores (and seem to be stuck at the second P_State) and that VoodooMonitor triggers a panic on my notebook. I wish there was a simple command line tool to generate P-States. This way people could test things, but without having to replace the boot file. Which in my opinion is a rather dated requirement.

MiniHack · November 20, 2010

A quick question that I hope you can answer. My output of BDMESG is below using an experimental DSDT on my Vostro 3500.

The key thing in this is that with this bootloader I have for the first time been able to generate p-states on my laptop despite my inability for me to remove the NullCPUPowerManagement.kext.

My question is though will these p-states be used if the disabler is still in place and how can I check this? Versions of CPU-X and voodoomonitor do not seem to work on the i5 CPUs so I'd appreciate a comment from someone who knows more than me!

BTW removing the disabler kext has been tried by me many times and my DSDTs have been much edited to try and enable that over the last months, so if AnVal is a genuine way to get speedstep working then this is real progression....

Thanks for your comments.

valv, great to see you back here and the newer booter, too. My bdmesg log from AnVaL 5.0.5 is following below. I like very much the updated BootHelp.txt. I don't over/ under clock my PC and respectively don't use these keys in the com.apple.boot.plist. Should you need any specific test to perform and report just give me the directions.

Yep, that because PStart=1 is working already - that disables Pstate0 (max. multi). Thats OK so.

You dont need PStart= if you dont have limited the multiplier in BIOS (like me : 9 vs 10 possible).

I can see also, that your VIDs , using moreVolt key got also wrong (Ex,Fx values insted of 1x,2x values).

That wromg values are so high that - the good - they are not used my the cpu (over any limit).

maxVolt seems also to be not used, does nothing . I dont know if there is some debug code which would show that, beside the

min/max Volt informatons shown in bdmesg

We must wait for valv, because its sure complex work to do all that for complete different cpus!

Same P-States!

Note: Apple clearly fixed a previously made programing error. Do you spot the error? I do

valv · November 20, 2010

This one is very experimental: Should be fixing all (or most) of the above behaviors.

I 'd need special feedback from guyz with i-series cpus about turbo.

From my other friends, I 'd appreciate to know if voltage, multiplier... issues are fixed now.

Thanks to all, and sorry for the mess

@dutchhokeypro, now that's a find. thank u for sharing

a previously made programing error.

I 'd add that this may not be a generic error for all models, though

Here we go (with boot_4)

The good: CPU Mhz now ok, 3000MHz (9*333 max), before 3333 Mhz

CPU: TSCFreq: 3330MHz

CPU: CPUFreq: 2997MHz // OK now

CPU: FSBFreq: 333MHz

The bad:

1. Min max Volts extreme high , and Min Volt

Voltage: min= 3575mV, max= 3112mV (before the min/max looked normal, MaxVolt had no effect)

2. Sticking with [FSB: 0Mhz, Bus-Ratio: 9] // 0 Mhz , perhaps some sign of bug for later computation?

Bus-Ratio: min=6, max=10 // CPU can this: yes, but busratio=9 set and also limited in BIOS=9, but perhaps later computed OK=dosnt matter

3. Now, also with PStart=1 (disables PState0) i get now only 3 Pstates , before i get 4 (PSstart=1) or all 5 (Pstart=0)

Now 8*,7*,6* are generated (missed 9*, 10* is disabled by PStart=1)

Can there be an bug / interfernence between PStart=1 and also set busratio=9 ?

Perhaps programm takes now (newest) busratio=9 and disables that 9* , because it thinks it is PState0 , but Pstate0 is 10* ?

4. VIDs now not Ex anymore but also much to high (normal range 12...25 hex).

Yeah. OS X 10.6.4 was apparently much more forgiving, but the slightest error now – like a wrong multiplier – is now punished with a much lower Geekbench score. I had 4033 with 10.6.4 and that dropped to a low 1998 after the upgrade. I solved this by applying the correct multipliers and I am back to 4033 with 10.6.5

The problem was that my in U-EFI _PSS values where used. I had no clue. Your code however appear to be fine. Just to make things clear.

Maniac10 · November 20, 2010

Here's my log, the only way to boot is to disable GE and run bdmesg in single user mode. I've booted with generate PS and CS, GE=no -s so you can take a look at the results for my i7. I can attach an ioreg dump and bdmesg with the kabyl boot to compare if you want.

That's not good.

2. Sticking with [FSB: 0Mhz, Bus-Ratio: 9] // 0 Mhz , perhaps some sign of bug for later computation?
Bus-Ratio: min=6, max=10 // CPU can this: yes, but busratio=9 set and also limited in BIOS=9, but perhaps later computed OK=dosnt matter

this is cosmetic, but should be fixed

Now 8*,7*,6* are generated (missed 9*, 10* is disabled by PStart=1)

Can there be an bug / interfernence between PStart=1 and also set busratio=9 ?

Perhaps programm takes now (newest) busratio=9 and disables that 9* , because it thinks it is PState0 , but Pstate0 is 10* ?

you need to use one or the other

4. VIDs now not Ex anymore but also much to high (normal range 12...25 hex).

this is a priority.

ok, I 'll be back asap; for the moment am removing boot_4

@valv,

This is bdmesg output on Dell Studio:-

valv: you need to use one or the other // To others: busration also has function for Pstate autogen, disables highest Pstate if busratio

Wreid : I set MoreVolt=0 (before 40) and also some ?? VIDs. I think that key must removed until fix, because =0 also makes not the normal(OK) VIDs generated without that key.

Now, removed MaxVolt and the moreVolt keys, added C-State gen

What do you meaned that my "The good" : fixed MHZ shown isnt good ?

CPU: Multipliers x10: max=90, min=60

CPU: MaxDiv/CurrDiv: 0x0/0x0

CPU: TSCFreq: 3330MHz

CPU: CPUFreq: 2997MHz /GOOD, before was wrong 3333

CPU: FSBFreq: 333MHz

Or do you mean with not good, that TSC freq - i dont know whats this is with 3333 Mhz?

C-State: Adding 3 states: C1 C2 C3

I thought my C2D E7400 has only C1, not C2+C3 . And the default is that C2+ are disabled and must enabled by:

EnableC2State=Yes Add C2 and lower supported states to _CST section (default: disabled).

EnableC3State=Yes Add C3 and lower supported states to _CST section (default: disabled).

Should i better add those keys with No to disable them active ?

EDIT: I added for test EnableC3State=No, but also C1+C2+C3 were generated.

So something must be wrong with the default disabled C2,C3,... . Looks that the major EnableCStates enables all - even the default disabled C2 and above)

TO OTHERS: Try to cut out the long bdmesg infos or use code box to post. Uncut/non codebox bdmesg postings take much space / long scrolling/eye lost the essenials of that postings - THANKS :wallbash:

valv · November 20, 2010

first of, Big Thank you to all!

@mitch_de, should the PStart key be removed now, as it makes redundancy with the bus-ratio injection? what do u think?

regarding more/lessVolt keys, it could be fixed with boot_5 (untested!).

c-states generation behaves differently. Note:

EnableC4State=Yes (for example): c4 and all previous states (supported by your cpu) would be generated.
If you use one of the EnableCXState keys, no need for the GenerateCStates key
EnableC4State=Yes (but cpu doesn't support it): c4 would not be generated
If u need to disable c3 (but keep the lower states): you need to remove EnableC3State altogether and add EnableC2State.

@kizwan, sorry for the delay, but I honestly don't know what to say other than: "u have pretty nice machines. I'd hope I could afford it ". Oh! and thank you for testing

Next attempt: boot5 is now useless

mitch_de · November 20, 2010

"mitch_de, should the PStart key be removed now, as it makes redundancy with the bus-ratio injection?"

Yes, if busratio is working and also it does limit PState i would comment the usage of busratio with " also limit fastest PSate to busratio".

Any hint, which way / tool can be used to show changing CPU MHz? MSR Tool dient work for me, and all others only show the max CPU MHz.

Reboot with boot5 , EnableC2=Yes, added volt keys again.... I´LL BE BACK

CoolBook !?

mitch_de · November 20, 2010

NO - i also thougth that would be nice, but it uses own Pstates (and reads/shows them).

You see i am BACK with boot5 and have some gift for you

boot5, moreVolt=40 , MaxVolt=1248 (with Versions before gave 3.x Volts)

C-State: Adding 3 states: C1 C2 C3

P-State: Added [Frequency 2331 MHz, FID 0x7, VID 0x25]

Also (more cosmetic) fixed debug info: Sticking with [FSB: 333Mhz, Bus-Ratio: 9], before FSB: 0 Mhz

Only i cant get rid of C3 State, even i use EnableC2State=Yes (should disable C3,C4,...)

kizwan · November 20, 2010

u have pretty nice machines.

Thanks. It would be very nice if the GPU is supported in OSX. The Dell is not a mistake since I bought it for work reason. The Asus was for OSX to be honest but it is a mistake since I didn't know it have Optimus switchable graphic card (poor advertisement). But at least it have good GPU for gaming.
